... Foodborne transmission gastroenteritis (AGE) outbreak occurred during a celebration lunch in July, 2016, Brazil. All stool samples tested were positive for noroviruses (NoV) and phylogenetic analysis revealed that strains were genetically close to GII.17 Kawasaki_2014. These findings indicated circulation of NoV GII.17 Kawasaki_2014 in the Brazilian population, associated with AGE outbreak. ...

... Transmissible gastroenteritis (TGE) is a highly contagious enteric disease of swine, which became infrequent with the appearance of porcine respiratory coronavirus (PRCV). TGE was last reported in Hungary in 2013 and the virus has not been found since, therefore a serological survey was planned to estimate the level of protection against it. 908 sera of sows from 93 farms were selected together wi ...

... While conducting rotavirus gastroenteritis surveillance in Vietnam, two G3P[8] rotavirus A specimens possessing an identical short RNA electropherotype were detected. They were RVA/Human-wt/VNM/0232/2016/G3P[8] and RVA/Human-wt/VNM/0248/2016/G3P[8], and recovered from 9 and 23 months old boys, respectively. The patients developed diarrhoea within one-week interval in March 2016 but in places >100 ...

... Salmonella enterica comprises many pathogenic serovars that are able to colonize a variety of animal hosts and therefore constitute an important source of zoonotic food-borne illness. Their pathogenicity can range from gastroenteritis to typhoid fever, and depends on a series of virulence factors that are regularly located on laterally acquired genetic elements. The regulation of these virulence f ...

... Noroviruses are the primary cause of non-bacterial acute gastroenteritis worldwide, and GII.8 belongs to a non-epidemic genotype with a limited understanding currently. In this study, we assembled the first GII.8 norovirus genome from China and clarified the temporal evolutionary process of this non-epidemic variant. Using the “4+1+1” application strategy with newly designed primer sets, the genom ...

... Ontario implemented a publicly-funded rotavirus (RV) immunization program in 2011. Our objectives were to evaluate its impact on hospitalizations and emergency department (ED) visits for acute gastroenteritis (AGE) five years after implementation.We performed a population-based longitudinal retrospective cohort study to identify hospitalizations and ED visits for RV-AGE and overall AGE in all age ...

... Porcine epidemic diarrhea (PED) is a contagious viral disease in pigs, caused by the coronavirus porcine epidemic diarrhea virus (PEDV). PEDV infection results in significant mortality in piglets in unvaccinated herds. Like many others RNA viruses, PEDV has high evolutionary rate and is prone to genetic mutations. In this study, we analyzed the complete genome sequence of the recently sequenced is ...

... Global outbreaks of norovirus (NOV) gastroenteritis are associated with the most prevalent genotype, GII.4. Mutations in the protruding domain 2 (P2 domain) of the norovirus major capsid protein (VP1) result in the emergence of various NOV variants, however, it is unclear whether the minor capsid protein (VP2) also affects the generation of VP1 variants. In this study, using a human 293T expressio ...

... Noroviruses are an important cause of acute gastroenteritis. The high incidence of norovirus is a reflection of its great genomic and antigenic variability resultant of evolutionary mechanisms, such as recombination. Herein, the main objective of this study was to characterize partially two regions of norovirus genome (RdRp and VP1) from fecal samples, collected in two different time periods (2009 ...

... Human astrovirus (HAstV) constitutes a major cause of acute gastroenteritis in children. The viral 5′ and 3′ untranslated regions (UTR) have been involved in the regulation of several molecular mechanisms. However, in astrovirues have been less characterized. Here, we analyzed the secondary structures of the 5′ and 3′ UTR of HAstV, as well as their putative target sites that might be recognized by ...

... During 2017, a G4P[6] group A rotavirus strain was identified in the feces of an Italian child hospitalized for acute gastroenteritis in Southern Italy. Nucleotide sequencing of the 11 genomic segments, revealed the G4-P[6]-I1-R1-C1-M1-A1-N1-T1-E1-H1 genotype constellation. Phylogenetic analyses of the gene segments investigated revealed high nucleotide sequence identities with G4P[6] RVA strains ...

... Norovirus is the leading cause of acute gastroenteritis worldwide with a yearly reported 700 million cases driving a $60 billion global socioeconomic burden. With no United States Food and Drug Administration approved therapeutics and the chance for severe chronic infection and life-threatening complications, researchers have identified the protease as a potential target. However, drug development ...

... In this study, we isolated, amplified and sequenced GII.3 norovirus (NoV) strains from children admitted to a department of pediatric gastroenterology presenting with acute gastroenteritis from September 2015 to March 2016. A total of 35 stool samples were collected and eight were GII.3 NoV positive, based on sequencing. The complete genome sequences were determined for two strains while partial g ...

... Norovirus is a major cause of non-bacterial acute gastroenteritis worldwide. Infection can be sporadic or result in widespread outbreaks. The surveillance of norovirus samples (n = 1591) obtained from patients with diarrhea in Thailand from January 2015 to February 2017 suggested that the predominance of norovirus GII.4 often seen in sporadic infection had been superseded by the emergence of GII.1 ...

... In India, G2P[4] strains are known to be the second most predominant group A rotaviruses causing acute gastroenteritis among children. This study was performed to determine the diversity within VP7(G), VP4(P), VP6(I) and NSP4(E) genes of 16 G2P[4] rotavirus strains detected in children hospitalized for acute gastroenteritis in Pune, Western India during 2009-2013. Fourteen strains showed G2-P[4]-I ...

... A number of novel viruses have been associated with canine gastroenteritis in recent years, from viral families as diverse as Caliciviridae and Picornaviridae to Parvoviridae and Circoviridae. The ability of many of these viruses to cause disease is uncertain, but epidemiological studies are continually adding to our knowledge of these potential pathogens. This review presents a summary of the lat ...

... Recent years have seen extremely fast development of new viral nanovaccines and diagnostic agents using nanostructures prepared by biological and chemical synthesis. We used spherical gold nanoparticles (average diameter, 15 nm) as a platform for the antigen for swine transmissible gastroenteritis virus (TGEV). The literature data demonstrate that immunization of animals with the TGEV antigen coup ...

... Norovirus (NoV), a major food-borne virus, causes non-bacterial acute gastroenteritis in humans. Berries are generally harvested from low-growing bushes by hand and are minimally processed before being sold to consumers. Therefore, the consumption of berries has been linked to numerous food-borne gastroenteritis outbreaks caused by NoV in many countries. We performed a survey of NoV contamination ...
